Stand-alone, contactless, active sensor providing the position and  rotation direction of the crankshaft by reading a ferromagnetic or  magnetic encoder wheel mounted on the engine crankshaft.  

Output signal used by the Engine Management System (EMS) to  determine the absolute engine position required by engine control  functions (injection, ignition,…).

Required for stop/start function and misfiring detection, allowing  compliance to the emission standards.

Benefits & Features
